Gl00my mentions this isn't absorbed by SeCreateAccessCheck and I just noticed that too. - We only need to perform security checks for a new object, in ObInsertObject, not if the object already existed. - Added proper backout+failure code in ObInsertObject if lookup failed, and also look out for mismatch/exists/collision cases (implemented using simple logic).
